A phone tablet selfie light is a portable lighting device designed to improve the quality of selfies and video calls taken with smartphones or tablets. These lights typically attach to the device, either through a clip or a suction cup, and provide additional illumination to enhance the lighting in selfies, especially in low-light conditions.

These lights have a suction cup mechanism that attaches to the back of your phone or tablet. They provide additional illumination for rear-facing camera shots as well as selfies.
